Member d indicates the plumb cut of a hip or valley` rafter and also indicates the cut of the sheeting which 5 is nailed to said rafters. The adjustments of said rafter miter are all made preferably with reference to' the member c. The angle that this member makes relatively to the upper surface of the metallic container g corresponds to the desired .pitch of the roof to be laid out. The angle that the @member d makes indicates the correct angle lfor the plumb cut of the hip or valley rafters. The angle to which the member c is adjusted determines the angle at which the seat on the plate of the common rafters, `-jack rafters or cripple rafters should be made. This member also will indicate the angle of cutupon the sheeting which joins at the hip or valley rafters, graduations h2 being marked on either of the flanges 71, f-or 71, of the metallic container g, the cut being made at the angle indicated by the member d when a set is made by said arm e upon said graduated scale. The angle that member fmakes with the edge of the metal- -`,liccasing g indicates the angle which the seat'jon the plate of the hip or valley rafters should make, .with the horizontal. Said member a is virtually a straight Hat bar pivoted on` a non-adjustable pin a and the inner end 1,2 .of which is connected to the inner end b2 of the member b by T-shaped connecting member z'. The member l) is also a Istraight bar and is pivotally attached to thestock casing g by a non-adjustable pin VVb". The member c has an oifset port-ion c5 below its pivot c and thus the inner end c2 makes an anglewith the remainder of said 40 member. Said inner Vend is also connected with said T-shaped connecting member z'. The member d is pivoted about an adjustable screw d and the portion d3 of said member below 'said pivot .is curved so that the inner end d2 is out of alinement with the remaining portion'of said member d. The inner endrlzof said Vmember isalso pivotally connected to said T-shaped connecting member "71. The connection by which the inner end v2 is connected to said member is by means of a pivot connectionz".V j The connec- .tion between the inner end b2 and said member i is made through thepivotvconnection 2.

Said connection is also connected toa link l through a pivot connection j3, said link Z being pivotally connected to a link m through an adjustable pivot connection ml said curved connecting link m being fastened at its other end to the inner end f2 of the member f through the non-adjustable pivot connection m2'. Said member f is substantially a straight member which is pivoted upon a pivot member f.' pivot connection for said members which are not adjustable relatively to said metallic casing in a slot are the pivot connections c and f as shown in Fig. l. The pivot connection d is movable relatively in the slot n. cut in the side g of the metallic casing. Said pivot connection o is movable relatively in the slot c cut in the si'de g2 of the metallic casing. The pivoted connection b is adjustable relatively in the slot p cut in the side g of the metallic casing and the pivot a is adjustable relatively in the slot f/ out in the side g of the casing. The pivot z" is adjustable relatively in the slot 7" cut in the side g2 of the metallic casing. The pivot connection y'2 is adjustable relatively to the slot s cut in the side g2 of the casing and the adjustable member m is adjustable relatively in the slot cut in the side g of 'the casing. As shown in Fig. 4l` the pivot connection d is made adjustable by being provided with a nut d4 threaded on a stud Z5 fastened to two spacers d6 and Z7 to each side of the member d. Said nut Z4 is made with a portion ZS which is slightly smaller in diameter than the remaining portion of said nut and which is exactly the same diameter as the circular apertures n and n2 that terminate each end of the groove a and the diameter of' said stud Z5 is exactly the same as the width of the slot n. The portion of said nut above said narrowest portion d8 thus forms a shoulder which is adapted to bear against said member g.

In Fig. 5 I sho-w a detailed view of a typical pivoted connection for the remainder ofsaid member. This connection b is a rivet which holds two space-rs b3 and b4 at each side of themember b. The head b5 of ,said stud like member is substantially the same diameter as the width of saidslot p soithat the sidesof said slot willform a guide wayV for the movement of said stud therein.

In Fig. l1 the portions f3 and f4 of said threaded together and hold the spacers f5 and f6 to said member 'f and the heads of each member pass through'theside members g2 and glrespectively. In Fig. l0 the portions ofthe adjustable pivoted connection fm receive the same numerical suffix as do the Similar parts in Fig. 4g thus said parts The only pivot connect-ion f shown in detail are m4; doesnotlha le a narrowedpertionibutslot n at tsbuter end.

In Fig. 6 I show how the master lever (Z can be set for and illustrates how the members e and Will disappear below the flanges ZL and z/ When the parts' are set to this degree and in Fig. l I show how the master lever can be lset for a root' having an ordinary pitch and the remaining members will assume their correct p0 sit-ion relatively thereto. The members a t0 f are held in position Within the container g by tightening the nut Z5 in the aperture n which terminates the slot-n at its i-nner end; As heretofore described the shoulder (Z5 on said nut exactly fits said aperture and thus When said nut is tightened the members can not move from place. To permit the members to be drawn :trom the container said nut Z4 is slacked off on the threaded pin (Z5 and the master lever is drawn outwardly 'trom said container so that the pivot reaches the upper end of said slot a bringing with it all of the other members a, Z), c, e and f respectively outwardly in their slots. When the members are in this position they assume their 4correct relative position to said master lever.
